Sometimes Microsoft ActiMates Interactive Barney starts playing
peekaboo on his own. This occurs because Barney's eyes are light-sensitive
and adjust to changes in lighting. Therefore, sudden light changes, such as
moving into a dark room, passing under a shadow in direct sunlight, or
passing under direct incandescent lighting, may cause ActiMates Barney to
start playing peekaboo.
